METHOD OF 'MAKING BOOTS AND SHOES.

Application filed July 20, 1920. Serial No. 397,695.

To all whom zmag/ concern:

Be it known that 1, FRANK E. ROBERTS, a citizen oli' the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful mprovements in Methods of h/lakingBoots and Shoes, of whichthe following is a specification. A

My invention relates to boots and shoes and has reference particularlyto the method of making boots and shoes of that class which have moldedoutersoles.

it has been the practice to mold the outersoles of certain kinds ofvboots and shoes, particularly womens boots and shoes, so as to `term asharply deiined angle or corner extending across the sole at the'junction of the shank with the fore-part, that is, just back of theball, so as to give a. pronounced arch to the shank which startsupwardly abruptly from the rear end olf the Jforepart. 1t also has beenthe practice to mold the shank of the outersole so that it was more orless V-shaped in cross-section with a sharply defined median ridge orcorner upon the exterior thereot1 extending from the rst mentionedtransverse corner or angle at the rear of the fore-part to the breast ofthe heel. This peculiar molding of the outersole, sometimes referred toas the Cottage Roof shape, has the advantage of improving the appearanceof the boot or shoe and also of stifening the shank.

1n my co-pending application. filed August 20, 1919, Serial Number318,771, 1 have illustrated and described a shoe whose outersole ismolded to the Cottage Root shape after the parts of the shoe have beenassembled upon the last, and my present invention has for its object toprovide a simple, expeditious, economical and efficient method of makingshoes of' this kind.

1n making a boot or shoe constructed as described in said application,the upper and innersole are first assembled upon a last and a bolsteringmember is placed in position upon the innersole at the place where thesharply delined bend or corner is desired in the outersole. Theoutersole is then secured in place and beaten down so as to utilize thebolstering member to give the desired shape to said outersole.

In making a boot or shoe in accordance with my present invention theparts may be assembled upon the last and secured together as describedin said application, but the beating down of the outersole `is effectedby blows or pressure delivered `onto said outersole by'any suitableinstrument, preferably a rotating wheel, in the peculiar 1 fashionhereinafterA described which stretches or crowds the material ot theoutersole toward theapex of the corner or bend with the result that avery sharply defined and accurately formed ridge or corner is produced.

In the accompanying drawings;

Figure 1 is a perspective view of the bottom portion of a shoe having aCottage Roof sole, said view including also a portion of Va beating downwheel which is shown by dotted lines.

Fig. 2 is a perspective view of the bolsterlng member hereinafterreferred to.

Fig. 3 is a perspective view of a portion of the beating down wheelhereinafter referred to.

Fig. 4 is a sectional detail of the wheel shown in Fig. 3. i

1n constructing the shoe of Fig. 1 the upper and inner sole are lastedand sewed together as usual after which the usual filler is spread overthe fore-part of the innersole between the edges of the upper. 1 nextplace upon the innersole, immediately at the rear of the filler, aholster member 9, Fig. 2, said bolster comprising a strip 14 extendingmore or less obliquely across the sole at the rear of the fore-partthereof and a stem 15 extending lengthwise of the shank 7 at the middlethereof. An unmolded outersole is then placed in position and sewed tothe up per and welt in the usual fashion after which the outersole istrimmed.

The rear end of the iforepart and the shank 7 ofi the outer sole arethen beaten down to shape them to the last and also bend or fold thesole sharply around the bolster member 9, the strip 14 of the latterproducing a sharply delined bend or corner 6 upon the exterior of thesole extending somewhat diagonally across the latter, and the stem 15 ofsaid bolster member giving to the shank a V-shape in cross-section witha sharply defined ridge 8 at the middle of the exterior of the shankwhich extends Jfrom the bend or corner 6 to the breSt of the heel,

In proceeding' according to my presentin- Vvention the beating downoftheoutersole is effected by After the-upper, inner sole,bolster mem-Vbers and outer sole have been assembled upon the last, and the inner andouter' soles last g, then placing a Ahave beensewed te the upper, theVshoe, still upon the last'is` manually presented, .as shown in F ig. l,to a rapidly rotating wheel l2 formed witharoughened or corrugatedperiphery v13 and is shifted about relatively thereto'so thattheelevationsot said periphery deliver a succession of glancing or wipingblows upon the tread side of the outersole asindicated by the arrows.The

wheel l2 is, causedto traverse both sides of corners 6 andA ridge 8, theworkman grasping the `opposite ends of' the shoe vwith his hands andpressin said shoe against wheel l2zwith `his hip.` he shoe is'presentedto wheel 12 sov that each peripheralV elevation of the wheel strikesthe'V outersolelat one side iof the line of the corner 6, er ridge 8that is being formed and wipes or slides on 'the sole toward said line.This method oiV procedure beats the outersole down againstthe last andbolstering means and Valso crowds the material of theoutersole more 'orless toward the corner 6 and ridge 8 with the resuitV that the latterare very accurately produced and `sharply defined. Moreover, this methodis expeditious and economical, as' by ita skilled workman cancompletelyniold the sole of a shoe of avery few seconds.
